Medical disclaimer
Last updated October 21, 2026
Top Rated Nootropics publishes independent reviews, ingredient research and comparisons of brain supplements. We aren't medical professionals. What we publish is general information, not medical advice, and it isn't a substitute for advice from a qualified professional who knows your health.
Before taking supplements
Speak to a doctor or pharmacist before taking any supplement we write about, especially if you take prescription medication or other supplements, are pregnant or breastfeeding, have a medical or mental-health condition, are under 18, or have concerns about interactions or side effects. Supplements can interact with medications, and they may not suit everyone.
Where we know of a specific interaction or caution for an ingredient, we flag it in that ingredient's guide and in the reviews of products containing it. Those flags are prompts for a conversation with your doctor, not a complete safety assessment.
About our research
We assess ingredients, published human studies, product labels and testing documents, and we report positive, negative and inconclusive research alike. A finding about an ingredient doesn't establish that a finished product containing it will have the same benefit.
Our ratings assess a formulation against our published method. They aren't guarantees of effectiveness, safety or individual results, and a product appearing on this site isn't a medical endorsement.
These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease.
If you have side effects
Stop taking the product and seek medical advice. In an emergency, call 911 or your local emergency number. In the US, you can report a suspected adverse event to the FDA through its Safety Reporting Portal.
